Will try to, but not sure if I'm able to cleanly set up a minimal use case. It looks like the actual crash was not the resource itself, but the two references to it in the .dist: <background file="logo.png" mime-type="image/png" alignment="bottomleft" scaling="none"/> <background-darkAqua file="logo.png" mime-type="image/png" alignment="bottomleft" scaling="none"/> Deciding for only one of those avoids the crash, and leaving the background one shows the logo on my macbook, with my configuration. I have no idea what exactly background-darkAqua is or does.

Happens as well on 12.5.1 (21G83). Xcode 13.3.1 (13E500a). Leaving out the one --resources parameter makes it run through without a crash. Edit: The resources directory consists of 3 files, de.lproj, en.lproj and logo.png. Removing logo.png makes the crash go away.

Thank you for mentioning TN2232, that looks like a viable way to do it manually, in-app. But is there a way for an app to piggy-back on certificates the user installed globally, accepted, via settings, and trusted - https://support.apple.com/en-us/HT204477?

Yes, this is about TCP connections to servers with self-signed TLS certificates. We also support client-side certificates, that has been implemented already. I currently don't expect to support that simultaneously, but who knows what kind of servers are out there. I'm unfortunately not able to link to our open source repo, the link gets rejected.
